While the actor is a Group and you can follow it, no posts are Announced. All the federation of posts is still driven by the individual communities within the feed. You’ll need to modify Lemmy to add the logic of subscribing to the constituent communities when you receive an Accept.
Also there are Add and Remove activities sent out whenever the feed owner manages the list of communities within which would need to be handled.
For the federating its a new kind of AP actor. I’ll be putting in a FEP for it in the near future, but its basically a “Group” that only cares about the “Following” collection.
